I have a wonderful used copy of a very hard to find, vintage, Disney Book, titled THE CIRCUS, featuring Toby Tyler.  The book is part of the World of Adventures series.  The book is dated 1978, and is very good condition.  There's some slight corner/edge bumping from being on my library shelf for so many years.  It has always been stored within a smoke free / pet free home.  Please feel free to ask any / all questions.  Thanks so much.  Take care and stay safe.
